Implement the interface to the AX88772 Ethernet controller.
|
||||
|
||||
This module implements the interface to the ASIX AX88772
|
||||
USB to Ethernet MAC with integrated 10/100 PHY. Note that this implementation
|
||||
only supports the integrated PHY since no other test cases were available.

ControllerHandle and ChildHandle in the form of a Unicode string. If the
|
||||
driver specified by This has a user readable name in the language specified by
|
||||
Language, then a pointer to the controller name is returned in ControllerName,
|
||||
and EFI_SUCCESS is returned. If the driver specified by This is not currently
|
||||
managing the controller specified by ControllerHandle and ChildHandle,
|
||||
then EFI_UNSUPPORTED is returned. If the driver specified by This does not
|
||||
support the language specified by Language, then EFI_UNSUPPORTED is returned.
|
||||
|
||||
@param [in] pThis A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
|
||||
EFI_COMPONENT_NAME_PROTOCOL instance.
|
||||
@param [in] ControllerHandle The handle of a controller that the driver
|
||||
specified by This is managing. This handle
|
||||
specifies the controller whose name is to be
|
||||
returned.
|
||||
@param [in] ChildHandle The handle of the child controller to retrieve
|
||||
the name of. This is an optional parameter that
|
||||
may be NULL. It will be NULL for device
|
||||
drivers. It will also be NULL for a bus drivers
|
||||
that wish to retrieve the name of the bus
|
||||
controller. It will not be NULL for a bus
|
||||
driver that wishes to retrieve the name of a
|
||||
child controller.
|
||||
@param [in] pLanguage A pointer to a Null-terminated ASCII string
|
||||
array indicating the language. This is the
|
||||
language of the driver name that the caller is
|
||||
requesting, and it must match one of the
|
||||
languages specified in SupportedLanguages. The
|
||||
number of languages supported by a driver is up
|
||||
to the driver writer. Language is specified in
|
||||
RFC 3066 or ISO 639-2 language code format.
|
||||
@param [out] ppControllerName A pointer to the Unicode string to return.
|
||||
This Unicode string is the name of the
|
||||
controller specified by ControllerHandle and
|
||||
ChildHandle in the language specified by
|
||||
Language from the point of view of the driver
|
||||
specified by This.
|
||||
|
||||
@retval EFI_SUCCESS The Unicode string for the user readable name in
|
||||
the language specified by Language for the
|
||||
driver specified by This was returned in
|
||||
DriverName.
|
||||
@retval EFI_INVALID_PARAMETER ControllerHandle is not a valid EFI_HANDLE.
|
||||
@retval EFI_INVALID_PARAMETER ChildHandle is not NULL and it is not a valid
|
||||
EFI_HANDLE.
|
||||
@retval EFI_INVALID_PARAMETER Language is NULL.
|
||||
@retval EFI_INVALID_PARAMETER ControllerName is NULL.
|
||||
@retval EFI_UNSUPPORTED The driver specified by This is not currently
|
||||
managing the controller specified by
|
||||
ControllerHandle and ChildHandle.
|
||||
@retval EFI_UNSUPPORTED The driver specified by This does not support
|
||||
the language specified by Language.
